"The type of technology we use here in WA and South Africa is acoustic technology."

Some120 acoustic receivers will be laid along the South West and South Coasts at intervals of 800 metres and from close inshore to a depth of around 200m. The receivers will be located at Rottnest Island, Hamelin Bay, off Walpole and at Bald Island.

"That recreates an array, or a curtain," says Mike. "So as a tagged shark swims by, it's detected by those receivers."

The acoustic transmitter attached to the sharks have a life span of around seven to ten years.

Listen to the interview from ABC South West Mornings as Mike explains the purpose of the project which is to discover why, when and where white sharks migrate to WA waters.
